"This disc is unreadable" error occurs when you use a Games on Demand game

You see the following error message when you try to play a Games on Demand game on your Xbox 360:

This disc is unreadable. It may be the wrong region for this console. Match the region of the disc to the console. Clean the disc with a soft cloth. Restart the console. For more help, go to www.xbox.com/support.

This problem can occur if you're not using the same profile used to purchase the game, or your Xbox 360 console can't read game files on the disc or on the hard drive.

Solutions

Solution 1: Check that you're using the Xbox profile used to purchase the game

Check that your Xbox profile is the same one used to purchase the game. If it is, go to Solution 2 to verify that your console has the license for the game.

Solution 2: Transfer the game license to your console

If you're using a different console than the one you used to purchase the game, you will need to transfer the content license to the console where you want to play the game.
